I picked up a spare stock air box for my 2020 Grom. I have both Koso tubes and DHM spacer. I’m going to mod the box and install it. Does anyone have this mod on an otherwise stock bike? What can I expect I specifically I am wondering about noise and if I will lose any low end torque. My plan is to do this first then if I like it to add the tb cam. I have it left over from a 2020 monkey I had. If I remember correctly I think the cam lost low /mid torque and woke up at higher RPM’s.
